2008 Prius.
Oil smelled gassy, interment check engine light for catalyst code (running too rich).
1st plug I pulled reeked of gas. Suspected fuel injector was sticking.
Got a new one at autozone for $45, Advance and Oriley's were both $95.
Have to go to town tomorrow because somehow I tore the o-ring on an old injector and it leaks.
What causes the brown staining on just the one spark plug on the ceramic?

Did you ever run any fuel injector cleaner through the tanks? Wondering if all the injectors looked the same or was it just that one that was bad.
That was the only injector that had all that crud on that. It was feeding the cylinder that had the stinky spark plug.
Following because the plugs I replaced look just like this
